How can we improve Design Master?

Merge Circuits

Add the option to merge two circuits together.

One of the circuits would end up as a space with nothing connected to it, no fixed loads, and no locked breaker or wire sizes.

The other would have all of the devices that were originally connected to the two devices, the sum of the fixed loads from the two circuits, and all the fixed breaker and wire sizes from the two circuits.

This command would be added to the existing "Swap and Copy Circuit" command. I guess we'd have to rename it to "Swap, Copy, and Merge Circuits". If we add anything else, we'll need a more generic name for that command!
